  • This paper reports the principle of displacement eddy current sensors and highlights the advantages compared with other non-contact sensors. Key factors that influence the sensor accuracy are presented. An experimental study has been undertaken into the effects of different target metals measured by the sensors. Based on a theoretical analysis, the methods to overcome the inhomogeneity (electrical run out) of eddy current sensors are discussed. Some initial results are presented to demonstrate… CONTINUE READING
